This paper reports past performance data for document delivery services provided by two libraries at University of Minnesota (Walter Library, Institute of Technology Libraries) and results of survey of faculty served by these services. Differences between users and nonusers, reasons for nonuse, and correlates of extent of use are discussed. (EJS)

Relationships between interest in natural sciences and technology and perceived ability, success, and invested effort were studied in Swedish secondary school students. Interests were accounted for by logical orientation and practical value. Interests and grades were strongly correlated, but correlations between interests and effort and vocational…

Separate dimensions of infant cognition were compared with parental general- and specific-cognitive abilities for 182 adoptive and 164 nonadoptive families. More parent-offspring resemblance was present when 24- rather than 12-month Bayley factors were used. Bayley factors were more related to parental g than to specific abilities. (Author/RD)

Reports research results into a methodology for determining similarity between queries characterized by Boolean search request formulations and discusses similarity measures for Boolean combinations of index terms. Rationale behind these measures is outlined, and conditions ensuring their equivalence are identified. Results of an experiment…

Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…

Two methodological issues involved in determining the relationship between learning and general intelligence were examined: (1) the use of learning strategies in a paired-associate task and (2) the importance of time (rather than errors) in the measurement of learning efficiency. (Author/RD)

This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…

Individual Education Plans (IEPs) and 504 Plans often recommend the use of accommodations to facilitate the learning of classroom material by students with disabilities. Since the Individuals with Disabilities Education Act (IDEA) in 1997, students with disabilities are expected to participate in state and district-wide assessments, using…

"Data Trends" reports present summaries of research on mental health services for children and adolescents and their families. The article summarized in this "Data Trends" uses data from a multilevel longitudinal study, the Project on Human Development in Chicago Neighborhoods (PHDCN), to investigate possible effects of neighborhood residence on…

In this Research-to-Results Brief, the author discusses the importance for policymakers, taxpayers, and the media to recognize the diversity in children's circumstances, because this recognition affects the number of children believed to need varied services and the magnitude of the challenge of meeting that need. Many researchers have developed…

The purpose of the present study was to evaluate the differences in demographic characteristics, motivational orientation, self-efficacy, and attitudes about technology between students who enrolled in a course offered in the traditional setting and those enrolled in the same course online. The two groups, each comprised of 27 students, were…

This paper examines issues related to the statistical power of impact estimates for experimental evaluations of education programs. The focus is on "group-based" experimental designs, because many studies of education programs involve random assignment at the group level (for example, at the school or classroom level) rather than at the student…

This present research reveals how beer advertising affects adolescents' knowledge of beer brands, drinking attitudes, and drinking behaviors. In addition to traditional psychological approaches for measuring media effects on alcohol-related behaviors and attitudes, market research advertising tracking methods were included to permit a clearer and…

Responding to questions regarding what research tells us about the importance of school size to student achievement, this report reviews recent research on the topic. It concludes that to the extent that small schools are better able than large schools to create forward planning conditions, then small schools appear to be a promising strategy. The…

The aim of this research was to discern the effects of computer assisted English instruction on English language preparatory students' attitudes towards computers and English in a Turkish-medium high school with an intensive English program. A quasi-experimental time series research design, also called "before-after" or "repeated…
